To 60% whmn it ntay concern:

Be it known that I, ARTHUR JUNOD-TURIN, a citizen of Switzerland, and aresident of St. Oroix, canton of Vaud, Switzerland, have inventedcertain new and useful Improvements in Mechanical Musical Instruments,of which the following is an exact specification.

My invention relates to mechanical musical instruments, and moreespecially to a device to for holding the note-disks of suchinstruments, and has for its purpose to provide means for easily movingthe axle around which the note-disks turn. The moving of this axle hasthe purpose that between the I5 rows of perforations or pins of thenote-disks further rows of such perforations or pins may be provided,which after moving the situation of the center of the note-disks bymoving the axle around which they turn engage with the star-wheels orsounding-tongues of the instrument, so that several music-pieces can beplayed by means of one note-disk or that music-pieces can be playedwhich are three or four times as long as the pieces which can be playedin case the center of the music-disks cannot be moved and theintermediate rows of pins or perforations are not provided.

The devices hitherto used for displacing the center of the music-disksconsist of a slide guided in the base-plate of the instrument, to

, which slide the axle around which the musicdislzs turn is fixed. Thisslide is provided with a projection situated so as to be moved by meansof an eccentric, a cam or stepped 5 wheel, or the like. Thisconstruction has, however, the disadvantage that the device is verycomplicated and makes the putting in of new note-disks more difficult.These disadvantages are done away with by the presarm or holder, whichserves for pressing the note-disks down, which holder is journaled sothat it can be simultaneously turned and moved in its longitudinaldirection, thereby taking the note-disks along. The moving of thisholder can be effected in any convenient way, and the mechanism requiredfor this purpose can be situated above the note-disk,

so that the guide of the disk is very simple and does not at all hinderthe putting in of new note-disks.

In the accompanying drawings, a is the holder, provided with rollers b bfor pressing the note-disk t' down. The holder or is journaled at c andd, so that it can be turned and at the same time moved in itslongitudinal direction. The moving of the holder at in its longitudinaldirection is effected by means of the cam or stepped wheel 6 and of thespringf.

In the construction shown in Figs. 1 to 4 the holder at is provided withthe projection 0, which when turning the holder engages with acorresponding cut-out g, provided in the axle 72, around which thenote-disk i turns. This axle his fixed to aslide, so that the same canbe moved.

In the modification shown in Figs. 5 and 6 the axle t passes through theholder CL and is heldin its position by means of a spiral spring Z,tending to press the axle downward. The lower end of the axle t in thismodification moves in a slot m of the base plate. In this latterconstruction the putting in of the note-disks is considerablyfacilitated, as the note-disks need not be put upon the axle i, but areplaced upon the base-plate, whereafter the axle t, which is drawn upwardby means of the handle 7c, is let loose, whereby the lower end willenter into theguide-hole of the note-disk.

It will be understood that the moving of the wheel in steps 6, the stepsof which wheel can be vertical, Fig. 1, or horizontal, Fig. 5, can beeffected in any convenicnt'way without changing the idea of myinvention. Also the form of the cam or stepped wheel and its effect uponthe holder may be varied in diifer- 5 cut ways.

Having thus fully described the nature of my said invention, What Idesire to secure by Letters Patent of the United States is 1. In adevice for displacing the center of the note-disks in mechanical musicalinstruments, the combination of a holder or arm for pressing thenote-disks down, an axle around which the note-disks turn, means forconnecting this axleto the holder or arm, with means for moving theholder in its longitudinal direction, substantially as described and forthe purpose set forth.

2. In a device for displacing the center of the note-disks in mechanicalmusical instruments, the combination of a holder or arm for pressing thenote-disks down, an axle around which the note-disks turn, means forconnecting this axle to the holder or arm, with a cam or stepped wheelfor moving the holder in its longitudinal direction, substantially asdescribed and for the purpose set forth.

3. In a device for displacing the center of the note-disks in mechanicalmusical instruments, the combination of a holder, an axle around whichthe note-disks turn, said axle being fixed in the holder, with a cam orstepped wheel, for moving said holder in its longitudinal direction,substantially as described and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
